Title: Method for Transmission Error Notification in VoDSL Gateway
Inventor: LEE JI YEON
IPC: H04L12/66
Filed: 2001-08-17
Abstract: PURPOSE: A method for notifying a transmission error in a VoDSL(Voice over Digital Subscriber Line) gateway is provided to set transmission error information in a parity bit included in a packet frame transmitted to a vocoder and notify the transmission error to the vocoder without adding specific data or using a control signal. CONSTITUTION: If an AAL2(ATM(Asynchronous Transfer Mode) Adaptation Layer 2) processing unit senses the loss of a frame by a transmission error while the frame received from an ATM network interface unit is processed(S10), the AAL2 processing unit sets transmission error information in the first parity region and the second parity region of a random packet frame(S12) and transmits the random packet frame to a vocoder(S14). The vocoder receives the packet frame from the AAL2 processing unit, analyzes the received packet frame(S16). The vocoder judges whether an error is generated in a parity bit on the basis of the first and second parity bits(S18). If the error is generated in the parity bit, the vocoder judges whether the first parity bit is set as '0'(S22). If the error is not generated in the parity bit, the vocoder decompresses and decodes the packet frame received from the AAL2 processing unit and converts the packet frame into an original voice signal(S20). If the first parity bit is set as '0', the vocoder recognizes the packet frame as the frame inserted in the AAL2 processing unit and recovers a lost frame on the basis of a previously processed frame(S24). If the first parity bit is not set as '0', the vocoder performs a correction work about the first parity(S26).
